  1. 1. Molecular analysis of transcription factors in uropathogenic E. coli adhesin operons

    Author : Stina Lindberg; Bernt Eric Uhlin; Åsa Sjöling; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; UPEC; E. coli; F1C; P fimbriae; cross-talk; FocB; PapB; crystal structure; OMVs; Medical microbiology; Medicinsk mikrobiologi; molekylärbiologi; Molecular Biology;

    Abstract : The main causative agent of human urinary tract infections is the uropathogenic Escherichia coli (UPEC) pathotype. It may cause disease due to its ability to express a number of bacterial virulence factors. Fimbrial adhesins are particularly important for the initial establishment of infection in the urinary tract. READ MORE

  2. 2. Pathogenecity-associated genes modulate Escherichia coli adhesion and motility

    Author : Annika E. Sjöström; Bernt Eric Uhlin; Ann-Beth Jonsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Escherichia coli strains typical of UPEC (uropathogenic E. coli) and NBM (newborn meningitis) isolates carry chromosomally located PAIs (pathogenicity islands) that are absent in non-pathogenic E. coli strains. The PAIs include genes for virulence factors such as toxins and genes coding for specific adhesins and pili/fimbriae formation. READ MORE

  3. 3. Mechanisms of P fimbriae cell activation

    Author : Maria Hedlund; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; type 1 fimbriae; LPS; glycosphingolipids; ceramide; E. coli; P fimbriae; mucosa; cytokines; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Microbial attachment to host cells plays a central role in the induction of inflammatory responses and the production of the disease. Uropathogenic Gram negative bacteria carry surface lectins that specifically recognize oligosaccharide receptor epitopes expressed on glycolipids or glycoproteins. READ MORE

  4. 4. Antibiotic Resistance and Fitness of Escherichia coli in the Infantile Commensal Microbiota

    Author : Nahid Karami; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ampicillin; tetracycline; in vivo fitness; persistence; gene transfer; intestinal; blaTEM Escherichia coli;

    Abstract : Microbial resistance to antibiotics is a growing problem worldwide. Resistance develops not only in microbes which are the targets of the antibiotic treatment, but also in those belonging to the normal microbiota of the treated host. Little is known on the ecological consequences of antibiotic resistance in commensal bacteria. READ MORE

  5. 5. Febrile Urinary Tract Infection: P fimbriae, Innate Host Response and Bacteremia

    Author : Gisela Otto; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []

    Abstract : Urinary tract infections (UTI) are among the most common human infections, and febrile UTI with bacteremia the most severe form. The relation between bacteria and host decides disease severity. The dominating uropathogen is Escherichia coli (E. coli). READ MORE
